// Simple example

@Component
public class MyCommandLineRunner implements CommandLineRunner {

    private static final Logger logger = LoggerFactory.getLogger(MyCommandLineRunner.class);

    @Override
    public void run(String... args) throws Exception {
        logger.info("This is a sample log message from CommandLineRunner.");
    }
}

// Example : Bring data

@Component
public class CLRunner implements CommandLineRunner {

  @Autowired
  private final RoomReservationService roomReservationService;
  @Autowired
  private final RoomRepository roomRepository;

// No need for constructor if @Autowired is used
//  public CLRunner(RoomRepository roomRepository) { 
//    this.roomRepository = roomRepository;
//  }

  @Override
  public void run(String... args) throws Exception {
    // Testing by printing table repository data
    List<Room> rooms = roomRepository.findAll();
    rooms.forEach(System.out::println);
    
    
    // Testing by printing service output
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    Date reservationDate = dateFormat.parse("2022-02-14");
    List<RoomReservation> roomReservations = roomReservationService.getReservationsByDate(reservationDate);
        
    // Display the room reservations in the console
    System.out.println("Room reservations for " + dateFormat.format(reservationDate) + ":");
    for (RoomReservation roomReservation : roomReservations) {
       System.out.println("Reservation ID: " + roomReservation.getReservationId());
       System.out.println("Room Number: " + roomReservation.getRoomNumber());
       System.out.println("Guest Name: " + roomReservation.getGuestName());
       System.out.println("Reservation Date: " + dateFormat.format(roomReservation.getReservationDate()));
       System.out.println("-------------------------");
     }
   }
}
